General annotation (Comments)

Function	Catalytic histone acetyltransferase subunit of the RNA polymerase II elongator complex, which is a component of the RNA polymerase II (Pol II) holoenzyme and is involved in transcriptional elongation. Elongator may play a role in chromatin remodeling and is involved in acetylation of histones H3 and probably H4. May also have a methyltransferase activity. Involved in cell migration By similarity.
Catalytic activity	Acetyl-CoA + [histone] = CoA + acetyl-[histone].
Cofactor	Binds 1 4Fe-4S cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine By similarity.
Subunit structure	Component of the RNA polymerase II elongator complex (Elongator), which consists of IKBKAP/ELP1, STIP1/ELP2, ELP3, ELP4, ELP5 and ELP6. IKBKAP/ELP1, STIP1/ELP2 and ELP3 form the Elongator core complex. Elongator associates with the C-terminal domain (CTD) of Pol II largest subunit. Interacts with IKBKAP/ELP1 By similarity.
Subcellular location	Cytoplasm By similarity. Nucleus By similarity.
Sequence similarities	Belongs to the ELP3 family. Contains 1 N-acetyltransferase domain.
